How does microeconomics relate to macroeconomics? (3 points) 70. Recent decades have seen a trend toward globalization, which means that buying and selling in markets have crossed national borders to an increasing extent. As a result, firms and workers from different countries are increasingly interconnected. Globalization has occurred for a number of reasons. List three reasons and briefly describe their effect contributing toward globalization. (5 points) 71. The formal study of economics began when Adam Smith (1723-1790) published his famous book The Wealth of Nations in 1776. In the first chapter of The Wealth of Nations, Smith introduces the idea of the division of labor. Define "division of labor" and illustrate with an example.

Computing the Steady State: Consider the Solow model discussed in class where output is given by Y = At KL and capital accumulation is given by: AKt = Kt+1-Kt = sYt-8Kt where s is the fixed constant savings rate and 8 is the depreciation rate. (a) Suppose At grows at 1%, a = 1/2, Kt grows at 4% and Lt grows at 2% per year. What is the growth rate of Y? About how many years will it take for income to double? (b) Does the production function display constant returns to scale? (c) Solve for the steady state level of capital (hint: set K = Kt+1= K*). How does the steady state level depend on the savings rate s and the depreciation rate of capital 8. (d) If a = 1, s = 0.05, 8 = 0.1, A = 4, and L = 3.5, what is the steady state level of capital? (e) If there was a sudden increase in technology A in the economy, what would happen to the steady state level of capital in the economy? How would wages evolve along the transition to the new steady state?

Consider the Solow model we discussed in class. The expression for total output and the dynamics of capital per worker are given by the following expressions: Y = AK L where A is the exogenous Solow residual, y is output per worker, and is the depreciation rate of capital. Ak = sy - 8k (a) Using the information given above, find the fundamental Solow equation. Find an expression for steady state capital per worker. (b) What happens to steady state capital if depreciation rate goes up? (c) Suppose that this economy consists of two types of households: laborers and capitalists. Capitalists own all the capital stock K and are paid a rental rate equal to the marginal product of capital. Find an expression for their share of national income. (d) Assume that laborers save none of their income. If capitalists save 30% of their income, the parameter a = 0.3, and the parameter = 0.1, what is the aggregate saving rate s? Will income inequality between capitalists and laborers worsen over time?

If an economy moves from a steady state with positive population growth to a zero population growth rate, then in the new steady state, total output growth will be and growth of output per person will be A) lower; lower B) lower; the same as it was before C) higher; higher than it was before D) higher; lower 3. In a steady-state economy with a saving rate s, population growth n, depreciation rate 8, and labor-augmenting technological progress g, the formula for the steady-state ratio of capital per effective worker (k*), in terms of output per effective worker (f (k*)), is A) sf (k)/(8+n+g). B) s/((f(k))(8 +n+g)). C) f(k)/((s)(8+n+g)). D) (s-f(k))/(8+n+g).

Annuity pricing a) An annuity is a financial instrument that pays out a constant amount of income per period for as long as the annuitant (i.e. annuity purchaser) is alive. Let P be the expected present value of annuity payments. Let a denote annuity income payment per period, m denote the probability of dying by next period (a.k.a mortality rate) and r denote the interest rate. Use the recursive asset pricing formula a + EP' 1+r P= to show that P = a r+m b) Suppose that an elderly annuitant has 500,000 in wealth and uses this wealth to purchase an annuity. Calculate the annual payment that the annuitant should expect if r = 0.05 and m = 0.03 per year. Explain how your answer is related to equilibrium economic profit of a financial institution that issued the annuity. (ii) Life insurance premium A life insurance policy is a financial contract that collects a premium of p per period from the insured and pays out a lump sum benefit B upon the death of the insured. Let m denote the mortality rate, r denote the interest rate and V denote the expected present value of economic profits of the insurance company on this policy. Use the recursive asset pricing formula v= P+ EV' 1+r to express equilibrium life insurance premium, p, through exogenous variables. Explain your answer and show all work. (iii) Loan calculators Suppose that loan of size S is repaid over T periods with equal per-period payments p and interest rate on the loan r. Initial loan size has to be equal to the present value of the payments: S=1+r+ (1+r) + ++ P (1+r) a) Calculate a monthly payment on the following mortgage. Annual interest rate is r = 0.06, mortgage term is 30 years, loan size S = 200,000. (Hint: since you are asked about the monthly payment, present value should be discounted at a monthly frequency. Start with figuring out the monthly interest rate and the mortgage term expressed in months, then apply the formula). b) Jill would like to buy a car that costs S=20,000. The dealer offers her a 60-month loan with 0 down and a monthly payment p = 421. Calculate the annual interest rate on this loan using Excel. Take the following steps: 1. Generate a column of 40 monthly interest rates, with r = {0.001,0.002,...,0.040), say column A, starting with Al. 2. Use the geometric series formula to express the present value of payments through p, T and rm, where I'm is the monthly interest rate. Plug in the numeric value for p, 7 and put this formula into cell B1. Have the formula refer to the interest rate from cell A1. Select B1:B100 and press CTRL+D. This will copy the formula and generate a column of present values that correspond to different monthly interest rate. Pick an interest rate from a row whose cell B value corresponds most closely to S. 3. Convert the monthly interest rate that you found on step 2 into annual using the compounding formula..
